BREAK-LEVER LOCK FOR GUNS.

SPECIFICATION forming part of Letters Patent No. 667,051, dated January 29, 1901.

Application filed October 16, 1899.

- To all whom it may concern:

j which the slide also forms the safety Be it known that I, JASPER LEANDER ACK- ERMAN, of Monon, in the county of White and State of Indiana, have invented a new and useful Improvement in Break Lever Looks for Guns, of which the,following is a specification.

In the patent granted to me September 26, 1899, there is shown and described a means for locking the break-lever of a breech-loading gun to prevent-it from being opened by unauthorized persons, in which device a bolt entering the lever was actuated by a rotarybarrel turned by a detachable key.

. My presenttinvention comprises an organization of devices for accomplishing this result,:in which an external slide is made to lock said lever either through a bolt or by a direct engagement, or both, and in which the slide may be soorganized as to constitute the safety of the hammer-less gun, as hereinafter more fully described with,reference to the drawings, in which- .Figure l is a longitudinal section of the grip portion ofthe gun, showing the locking of the break-lever through a slide which acts both directly and also through a bolt and in 77 lockthe triggers, the gun being shown in the locked position and the slide also locked by a rotary barrel and key. Fig. 2 is a similar view, the parts being shown in an unlocked position. Figs. 3 and 4 are two views showing closed and open positions, respectively, in whichthe slide acts upon the looking-bolt through the intervention of a lever. Fig. 5 is a modification in which the slide operates upon the bolt directly through acam-slot; and Fig. 6 is a plan of a further modification in which the bolt does not enter the lower side of the break-lever, but comes up on one side of it. Fig. 7 is a detail of a further modification.

Referring to Figs. 1, 2, and 6, A represents the break-lever, which has a recess a on its under side to receive the end of the locking bolt B, which is constructed as a lever ful- To the lower end of which at its rear crumed upon a pin 1). the lever is jointed a bar 0,

end is jointed to a downward extension d from the external slide D,

downward extension 61 of the slide another bar E extends to and is jointed to the top of a lever G, fnlcrumed -on a support g and carrying on its sides a pin 9', that engages with the triggers. When the slide D is pushed forward, as in Fig. l, the lever B is thrown into the recess of the break-lever A and the lever G is turned to bring its pin 9' against thetrigtrers. Thisnotonlylocksthetriggers,

so that the gun is safe, but also locks the break-lever A, so that unauthorized persons may not open the gun and remove the car-' tridges or otherwise tamper with the same.

In some cases I may not employ the locklever B and bar 0, but may make the forward end of the external slide D bifurcated to embrace and hold the rear end of the breaklever, as shown in Figs. land 6, which makes a simpler and more directlock, or botli looking devices may be employed.

As another modification of my invention I may, as seen in Figs. 3 and 4, make the locking-bolt B to. slide vertically and operate it through a lever L and spring cam-face d on the external slide D,or, as in Fig. 5, the siideD may have ahorizontal extension dh'provided with an inclinedslot d, in which'a pin attached to the lower end of the bolt plays and isdirectly operated by theslide. M To look the slide'fl) in either its forwarderretracted position,'asn1alllock of the Yale. pattern is arranged with its rotary barrel H in vertical position just behind the slide, and hasa cam-head llon its lower end. A levercatch K is fulcrumed at the forward edge of the lock-case and its forward end is pulled up by a spring F. On the rear end of this catch the cam-head H of the rotary barrel of the lock bears. When this cam-head-is turned into one position, as shown in Fig. 1, it allows the spring F to pull the catch K up behind the extension (1 of the slide, so that the slide cannot be pulled back; but when the cam-head H is turned it acts upon the rear end of the catch and draws down the front end of the catch, so that it is out of the way of the rearward movement of the slide extension, the hooked end of the catch rising after the slide is drawn back and hooking in front of the extension (Z, as shown in Fig. 2, so that the slide is locked also in its open position. The

rotary barrel H, with cam-head H, is operated by a key J, which is carried by the owner of may arrange a hole in the gun-stock or frame of my invention of the lever in the prevent it from being deflected.

In Fig? 7 I show a further modification in which the slide Dhas a tongue thatentersa notch in the lever A instead of being made forked and embracing it, as in Fig. 6.

I would also have it understood that variousolher modifications may be made withoutdeparting from my invention, the leading feature of which is to be'found in the com= bination, with the break-lever, of an external slide arranged to lock said lever cit-her directly or indirectly.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The combination with the break-lever in a breech-loadinggun; of an external slide arranged to lock said lever and a separate locking mechanism for the slide substantially as and for the purpose described.

2. The combination with the break-lever in an external slide arranged to lock said lever, and an independent lock forlocking the slide arranged behind the same, substantially as and for the purpose set forth.

he combination with the break-lever,

and the trigger mechanism in a breech-load"- inggun of an external slide arranged to lock path of the swing, and so both the break-lever and the trigger mechanism and a separate lock for the external slide, as and for the purpose set forth.

4. The combination with the break-lever,

a breech-loading gun; of an external slide ar-.

ranged to engage with the break-lever exte riorly and directly, and a locking device for holding said slide to such engagement sub: stantially as described.

6. The combination in a breech-loadinggun; ofan external safety-slide and a look and key for locking said slide arranged behind the slidesubstantiaily as and for the purpose described.

7. The combination with an external safety-slide, havinga downward extension; of a rotary barrel-lock said barrel havim. a key the other arranged to engage with the slide extension and lock the same substantially as described.

8. The combination with the break-lever, a locking-bolt engaging the same, and an external slide acting upon said bolt and a looking device for the external slide, su bstantially as described.

In testimony whereof I have signed my name to this specification.
